Description

Technical Field

[0001] This utility model relates to the field of electric chainsaw technology, specifically to an electric chainsaw with a protective structure. Background Technology

[0002] An electric chainsaw is a woodworking power tool that uses a rotating chain saw blade for sawing. It is mainly used for cutting and processing wood and is widely used in forestry, timber processing, pruning and other operations, as well as timber processing in timber yards and sawing railway sleepers.

[0003] For example, the Chinese authorized patent (electric chainsaw) with announcement number CN221336893U includes: a housing; a control board disposed within the housing; a cutting tool mounted on the housing, including a cutting chain and a blade plate for supporting the cutting chain; a motor fixed within the housing for driving the cutting tool; and a fan fixed to the rotating shaft of the motor. The fan includes: first blades, a plurality of first blades arranged in a circular array; a rear baffle disposed on the side of the fan near the motor; and second blades disposed on the side of the rear baffle opposite to the first blades, the second blades being arranged in the same direction as the first blades. By setting the second blades, which are arranged in the same direction as the first blades, the second blades form an airflow seal when the fan rotates, thereby ensuring that the heat exhausted by the fan is discharged from the housing along a predetermined channel and does not flow back to the motor and the main board, thus effectively improving the problem of poor heat dissipation and easy high-temperature protection of existing electric chainsaws.

[0004] However, the protective guards of existing electric chainsaws only protect the hands, specifically the front part of the hand. The protection range is small, and the upper part of the arm and hand is easily injured by flying objects during use, or even slip out of the hand, resulting in low safety. Therefore, it does not meet the current needs. To address this, we propose an electric chainsaw with a protective structure. Utility Model Content

[0005] The purpose of this utility model is to provide an electric chainsaw with a protective structure to solve the problem mentioned in the background art that the protective guards of existing electric chainsaws only protect the hands, and only the front part of the hands. The protection range is small, and the upper part of the arms and hands is easily injured by flying objects during use, or even slip out of the hand, resulting in low safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric chainsaw with a protective structure, comprising: a handle, an engine at one end of the handle, a blade chain at one end of the engine, a positioning seat at the upper end of the engine, and the positioning seat being thermally fused to the engine, a protective component on one side of the positioning seat, a lithium battery at the other end of the handle, and a switch on the inner wall of one end of the handle.

[0007] Preferably, the protective component includes a connecting cover, the outer wall of which is provided with a protective cover, and the protective cover and the connecting cover are thermally fused together. A connecting notch is provided on the surface of the connecting cover near the center of the bottom surface, and the connecting notch penetrates the connecting cover.

[0008] Preferably, the protective component further includes an adjustment seat, and the top of the adjustment seat is heat-fused to the protective cover. The front surface of the adjustment seat is provided with an adjustment groove, and the adjustment groove penetrates the adjustment seat.

[0009] Preferably, a reinforcing arm is provided on one side surface of the adjusting seat, and the two ends of the reinforcing arm are fixed to the adjusting seat and the connecting cover, respectively.

[0010] Preferably, one side surface of the positioning seat is provided with a moving groove, and the moving groove extends vertically through the positioning seat, and the adjusting seat moves vertically along the moving groove.

[0011] Preferably, the front surface of the positioning seat near the top is provided with a fastener hole, and the fastener hole penetrates the positioning seat. A fastener is inserted into one end of the fastener hole, and the other end of the fastener passes through the fastener hole and the adjusting groove and is then threaded to a nut.

[0012] Preferably, the front and rear surfaces of the top of the engine are provided with mounting grooves, the upper end of the mounting groove is provided with a support handle, both ends of the support handle are provided with fixing bolts, and both ends of the support handle are inserted into the mounting groove and fixed to the engine by fixing bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides a protective component on the side of the engine. The protective component consists of a connecting cover, a protective cover, and an adjusting seat. When installing the protective component, the protective component is moved from top to bottom. The connecting cover is fitted onto the outside of the chain saw through the connecting notch, and the adjusting seat is inserted along the moving groove. The height of the protective component is adjusted according to the arm length of the user of the electric chainsaw. The adjusting seat can be moved up and down along the moving groove. After adjustment, it is fixed by fasteners. The connecting cover and the protective cover increase the protection range for the user's hands and arms, preventing injury from flying objects and improving safety. Furthermore, the adjustable protective component is suitable for users with different arm lengths, improving applicability. It solves the problem that the protective guards of existing electric chainsaws only protect the hands and the front of the hands, resulting in a small protection range. The upper part of the arms and hands is easily injured by flying objects during use, and even slippage occurs, leading to low safety.

[0015] (2) By setting a reinforcing arm on one side of the adjusting seat, the reinforcing arm moves up and down along the opening on one side of the moving groove when the adjusting seat moves along the moving groove. The reinforcing arm improves the stability of the connection between the adjusting seat and the protective cover, making the connecting cover and the protective cover less prone to shaking.
